Multisensory Fusion Training and 7, 8-Dihydroxyflavone Improve Amyloid-ß-Induced Cognitive Impairment, Anxiety, and Depression-Like Behavior in Mice Through Multiple Mechanisms.

Background: There is growing interest in the role of physical activity in patients with of Alzheimer's disease (AD), particularly regarding its impact of cognitive function, gut microbiota, metabolites, and neurotrophic factors. Objective: To investigate the impact of multisensory fusion training (MSFT) combined with 7, 8-dihydroxyflavone (DHF) on the behavioral characteristics, protein expression, microbiome, and serum metabolome using the AD model in mice induced with amyloid-ß (Aß). Methods: We assessed cognitive ability, anxiety-like and depression-like behaviors in Aß mice using behavioral measures. Western blotting was employed to detect the expression of relevant proteins. The 16S rRNA gene sequencing and metabolomics were used to analyze changes in the intestinal microbial composition and serum metabolic profile, respectively, of Aß mice. Results: The behavioral outcomes indicated that a 4-week intervention combining DHF and MSFT yielded remarkable improvements in cognitive function and reduced anxiety and depression-like behaviors in Aß mice. In the hippocampus of Aß mice, the combined intervention increased the levels of BDNF, VGF, PSD-95, Nrf2, p-GSK3ß and p-CREB proteins. Analyses of sequence and metabolomic data revealed that Bacteroides and Ruminococcaceae were remarkably more abundant following the combined intervention, influencing the expression of specific metabolites directly linked to the maintenance of neuronal and neurobehavioral functions. These metabolites play a crucial role in vital processes, such as amino acid metabolism, lipid metabolism, and neurotransmitter metabolism in mice. Conclusion: Our study highlighted that MSFT combined with DHF improves cognitive impairment, anxiety, and depression-like behavior in Aß mice through multiple mechanisms, and further validated the correlation between the gut microbiome and serum metabolome. These findings open up a promising avenue for future investigations into potential treatment strategies for AD.

Social capital and healthy eating among two ethnic minority groups in Yunnan Province, Southwest China: the mediating role of social support and nutrition knowledge.

Background: Although social capital has been linked to dietary intake particularly in disadvantaged populations, little is known about the mechanisms. This study aimed to investigate whether social support (SS) and nutrition knowledge (NK) mediate the association between social capital and healthy eating habits. Methods: A probability sample of two ethnic minority groups in Yunnan Province, Southwest China were included (n = 1,033, mean age 47.5 ± 14.7 years). Bonding and bridging social capital (BOC and BRC) were assessed with the Personal Social Capital Scale (PSCS-16). Dietary data were evaluated with the Chinese Healthy Eating Index (CHEI), a measure of diet quality which reflects adherence to the Chinese Dietary Guidelines. NK and SS were measured with a validated questionnaire and scale, respectively. Structural Equation Modeling was used to calculate the direct, indirect and total effects of social capital on CHEI scores. Results: The mean score of CHEI was 57.4 ± 9.8, which was significantly lower in men and older people. Low adherence to dietary guidelines were to observed in the consumption of dairy, beans, nuts, animal-source food vegetables and fruits. BOC and BRC were positively associated with CHEI score (ß = 0.37 and 0.38, all p < 0.05). Social support and nutrition knowledge mediated 45.9 and 39.5% of the total effect of social capital on CHEI score, respectively. Conclusion: Social capital appears to enhance adherence to dietary guidelines by improving nutrition knowledge and social support. Nutrition promotion programs therefore should consider incorporating strategies that foster social capital development, particularly in disadvantaged populations.

Meta-analysis of acupuncture treatment for cervicogenic headache.

OBJECTIVE: To analyze and evaluate the clinical effect of acupuncture on cervicogenic headache (CEH), and provide evidence-based basis for clinical selection of acupuncture for cervicogenic headache. METHODS: Databases including China Knowledge Network, Wanfang, VIP Chinese sci-tech journals, Chinese Biomedical, and PubMed were searched to collect clinical randomized controlled trials on the effectiveness of acupuncture in the treatment of CEH until November 2023. Statistical analysis was performed using the RevMan 5.4.1 software, and heterogeneity was assessed using the Q test (P value), allowing for the calculation of the combined effect odds ratio through either the fixed or random-effect model. Sensitivity analysis will be conducted by excluding articles with the highest weight, while the validity of the literature will be evaluated through the creation of a funnel plot to identify any potential biases. RESULTS: A total of 400 articles were retrieved, and eventually, 20 clinical randomized controlled trials were included in the analysis. Comparing with control, acupuncture exhibited a higher total effective rate in treating CEH. The cure rate was also higher in the experimental group, and improvements in short-term and long-term visual analogue scale scores outcomes were significantly greater than those in the control group. The quality-of-life scores were higher in CEH patients treated with acupuncture. Sensitivity analysis confirmed the stability and reliability of the pooled effect size results. The results of the funnel plot indicated the presence of publication bias. CONCLUSION: Acupuncture treatment is effective for cervicogenic headache relief and worthy of clinical application.

Eye-Hand Typing: Eye Gaze Assisted Finger Typing via Bayesian Processes in AR.

Nowadays, AR HMDs are widely used in scenarios such as intelligent manufacturing and digital factories. In a factory environment, fast and accurate text input is crucial for operators' efficiency and task completion quality. However, the traditional AR keyboard may not meet this requirement, and the noisy environment is unsuitable for voice input. In this article, we introduce Eye-Hand Typing, an intelligent AR keyboard. We leverage the speed advantage of eye gaze and use a Bayesian process based on the information of gaze points to infer users' text input intentions. We improve the underlying keyboard algorithm without changing user input habits, thereby improving factory users' text input speed and accuracy. In real-time applications, when the user's gaze point is on the keyboard, the Bayesian process can predict the most likely characters, vocabulary, or commands that the user will input based on the position and duration of the gaze point and input history. The system can enlarge and highlight recommended text input options based on the predicted results, thereby improving user input efficiency. A user study showed that compared with the current HoloLens 2 system keyboard, Eye-Hand Typing could reduce input error rates by 28.31 % and improve text input speed by 14.5%. It also outperformed a gaze-only technique, being 43.05% more accurate and 39.55% faster. And it was no significant compromise in eye fatigue. Users also showed positive preferences.

Comparative efficacy of different types of exercise modalities on psychiatric symptomatology in patients with schizophrenia: a systematic review with network meta-analysis.

This network meta-analysis investigated the effects of 8 types of physical exercises on treating positive symptoms, negative symptoms, general psychopathology, and the Positive And Negative Syndrome Scale (PANSS) total score in patients with schizophrenia. The methods adhered to PRISMA guidelines and used the Cochrane risk of bias tool for quality assessment, and Stata software for data analysis. Data were sourced from PubMed, Embase, Web of Science, and the Cochrane database up to August 15, 2023, following PICOS principles. A total of 25 studies including 1441 participants were analyzed. Results showed that resistance exercise seems to be effective for improving positive symptoms, while Yoga was more effective for negative symptoms. Low-intensity aerobic exercise was optimal for general psychopathology, and Yoga was effective in improving the PANSS total score. The study concluded that yoga and aerobic exercise demonstrated superior performance, but the impact of exercise on patients with schizophrenia is also influenced by individual factors and intervention dosages. Therefore, a pre-assessment of patients considering factors such as interests, hobbies, and physical capabilities is crucial for selecting appropriate exercise modalities.

Influence of Various Flame Temperatures of the Gun Propellant on the Effectiveness of the Erosion Inhibitor and Relevant Mechanisms.

The development of high energy gun propellants faces significant challenges in terms of erosion, partly due to the inadequate effectiveness of erosion inhibitors. In this paper, the influence of quite different flame temperature of five gun-propellants on erosion-reducing efficiency of four representative inhibitors materials (talc/TiO2/ PDMS/Paraffin) were studied in vented erosion vessel tester. From aspects of morphologies and element compositions of erode steel samples, as well as the pressure and heat generated by propellant burning, the relevant erosion-reducing processes and mechanisms were discussed. The results indicated that erosion inhibitors should be appropriately selected according to the type of gun propellant. The erosion of gun propellants having extremely high flame temperature of 3810 K were hardly reduced using talc, TiO2, and PDMS inhibitors, which can generate numerous solid particles aggravating the melt-wipe process. While paraffin exhibits a uniquely positive erosion-reducing efficiency for the gun propellant having a flame temperature of 3810 K, that was attributed to the mitigated melt-wipe process. The inference was further supported by the high-volume cooling gas, resulting from the higher burning pressure of propellants loading with paraffin and excellent heat absorption capacity of paraffin tested with propellants having higher propellant flame temperature. The obtained results indicated that the factors of flame temperature of gun propellants should be taken into the design and composition optimization of an effective inhibitor. This work could provide potential reference for the development of future novel inhibitors, which serves as high energy gun propellants.

[Relationship between dietary nutrition and chronic disease of Jinuo Minority residents aged 20-80 in Jinghong District in 2020].

OBJECTIVE: To analyze the relationship between food intake and chronic diseases of Jinuo Minority residents living in Yunnan Province. METHODS: A total of 392 Jinuo Minority residents 20-80-year-old among 304 families(male 135, female 257; aged 20-49 years old 140, aged 50-59 years old 136, aged 60-80 years old 116)in Jinghong District in Yunnan Province were selected with stratified multistage cluster sampling method. To apply the method of food frequency questionnaire and questionnaire survey obtain the condition of dietary structure and overweight or obesity, diabetes and dyslipidemia among Jinuo Minority in the past 12 months. Non-conditional Logistic regression analysis was utilized to analyze the correlation between food intake and chronic diseases. RESULTS: In 2020, the prevalence of overweight/obesity, hypertension, diabetes and dyslipidemias among Jinuo adults in Jinghong District were 38.8%(n=152), 19.1%(n=75), 3.6%(n=14)and 26.3%(n=103). Jinuo residents aged 20 and above who have consumed noodle and instant noodle(OR=1.677, 95%CI 1.028-2.736), fermented soybean curd(OR=3.056, 95%CI 1.853-5.038), grass carp(OR=2.245, 95%CI 1.270-3.971), ethnic food/peanut(OR=1.975, 95%CI 1.162-3.355) were more likely to experience overweight/obesity compared to those who did not consume them. On the other hand, individuals who consumed snacks/bread(OR=0.322, 95%CI 0.190-0.545) were less likely to develop overweight/obesity compared to those who did not consume them. Jinuo residents aged 20 and above who have consumed other cereals and cereals products, such as buckwheat(OR=7.029, 95%CI 1.494-33.070), were more likely to develop diabetes than those who did not consume them. And those who have eaten cabbage vegetables(such as cauliflower/cabbage)(OR=0.155, 95%CI 0.034-0.708), and kernel fruits(such as apple/pear)(OR=0.227, 95% CI 0.069-0.743) were less likely to develop diabetes than those who did not consume them. Adults who consumed cooked meat and other livestock and poultry, such as donkey/horse meat(OR=9.676, 95% CI 1.418-66.027), were more likely to cause dyslipidemias compared to did not consume them. Conversely, individuals who consumed root vegetables(such as radish/lotus root)(OR=0.405, 95%CI 0.204-0.803), cooked pork from animal foods(OR=0.482, 95%CI 0.263-0.885), snacks/snack bread(OR=0.590, 95%CI 0.357-0.974) and plum blossom(OR=0.173, 95%CI 0.038-0.793) were less likely to develop dyslipidemia than those who did not consume them. CONCLUSION: In Jinghong District, the overweight/obesity of Jinuo adults aged 20-80 was positively correlated to the consumption of noodles and instant noodles, fermented bean curd, grass carp, and ethnic food/peanut. And there was a negative correlation with the consumption of snacks/bread. Regarding diabetes, a positive correlation was observed with the consumption of other grains and products, while negative correlations were found with the consumption of cabbage vegetables and kernel fruits. For dyslipidemias, there was a positive correlation with the consumption of cooked meat and other livestock and poultry, and negative correlations were identified with the consumption of root vegetables, cooked pork from animal foods, snacks/snack bread, and prunes.

Complex effects of testosterone level on ectoparasite load in a ground squirrel: an experimental test for the immunocompetence handicap hypothesis.

BACKGROUND: The immunocompetence handicap hypothesis suggests that males with a higher testosterone level should be better at developing male secondary traits, but at a cost of suppressed immune performance. As a result, we should expect that males with an increased testosterone level also possess a higher parasite load. However, previous empirical studies aimed to test this prediction have generated mixed results. Meanwhile, the effect of testosterone level on parasite load in female hosts remains poorly known. METHODS: In this study, we tested this prediction by manipulating testosterone level in Daurian ground squirrels (Spermophilus dauricus), a medium-sized rodent widely distributed in northeast Asia. S. dauricus is an important host of ticks and fleas and often viewed as a considerable reservoir of plague. Live-trapped S. dauricus were injected with either tea oil (control group) or testosterone (treatment group) and then released. A total of 10 days later, the rodents were recaptured and checked for ectoparasites. Fecal samples were also collected to measure testosterone level of each individual. RESULTS: We found that testosterone manipulation and sex of hosts interacted to affect tick load. At the end of the experiment, male squirrels subjected to testosterone implantation had an averagely higher tick load than males from the control group. However, this pattern was not found in females. Moreover, testosterone manipulation did not significantly affect flea load in S. dauricus. CONCLUSIONS: Our results only lent limited support for the immunocompetence handicap hypothesis, suggesting that the role of testosterone on regulating parasite load is relatively complex, and may largely depend on parasite type and gender of hosts.

Advanced fabrication approach for innovative triple base propellants with enhanced continuous fracture resistance.

This paper initially contrasts the solvent-based and solventless molding processes, subsequently optimizing a sustainable and efficient solventless molding route for both STP and SLTP. Key physicochemical parameters such as extrusion rate, residual volatile solvents, moisture content, and apparent density of both propellant types are meticulously compared. Furthermore, the orientation of crystal particles and the structure of the matrix-bound interface are analyzed. Comprehensive examination of triaxial progressive failure phenomena-including static thermal mechanical responses, quasi-static structural deformation, and dynamic structural damage-is conducted, leading to the formulation of a damage mechanism and model. Subsequently, a structural mechanics model for nitroguanidine micrometer rod-reinforced triple base propellants is established, quantitatively evaluating the influence of nitroguanidine crystal arrangement angles on the structural strength of both propellant types. This study furnishes a theoretical foundation for specialized internal structural and mechanical behaviors through theoretical computations.

CFD-DEM Evaluation of the Clustering Behavior in a Riser-the Effect of the Drag Force Model.

Riser reactors are frequently applied in catalytic processes involving rapid catalyst deactivation. Typically heterogeneous flow structures prevail because of the clustering of particles, which impacts the quality of the gas-solid contact. This phenomenon results as a competition between fluid-particle interaction (i.e., drag) and particle-particle interaction (i.e., collisions). In this study, five drag force correlations were used in a combined computational fluid dynamics-discrete element method Immersed Boundary Model to predict the clustering. The simulation results were compared with experimental data obtained from a pseudo-2D riser in the fast fluidization regime. The clusters were detected on the basis of a core-wake approach using constant thresholds. Although good predictions for the global (solids volume fraction and mass flux) variables and cluster (spatial distribution, size, and number of clusters) variables were obtained with two of the approaches in most of the simulations, all the correlations show significant deviations in the onset of a pneumatic transport regime. However, the correlations of Felice (Int. J. Multiphase Flow1994, 20, 153-159) and Tang et al. [AIChE J.2015, 61 ( (2), ), 688-698] show the closest correspondence for the time-averaged quantities and the clustering behavior in the fast fluidization regime.

Epidemiological Evaluation of Bacillus cereus-Induced Foodborne Outbreaks - China, 2010-2020.

Introduction: Bacillus cereus (B. cereus) is a common gram-positive bacterium that contaminates starch-rich food and can cause outbreaks of foodborne diseases. This study describes the characteristics of outbreaks caused by B. cereus in China during 2010-2020 and explore the possible reasons for changes in the number of outbreaks over time. Results of this analysis can efficiently help guide and allocate public resources to prevent B. cereus-caused foodborne diseases. Methods: Descriptive statistical methods were used to analyze the data on B. cereus outbreaks in China during this period. The data were identified and reported at all levels in China through National Foodborne Disease Outbreak Surveillance System. Results: From 2010 to 2020, a total of 419 foodborne outbreaks prompted by B. cereus were reported in China, leading to 7,892 cases, 2,786 hospital admissions, and 5 fatalities. The bulk of the outbreaks were recorded in the summer, primarily between May and September. The most recurrent food vehicle was linked with rice or flour-based products, notably those made with rice or fried rice. School canteens bore the brunt of the B. cereus outbreaks. In multifactor outbreaks, food contamination was identified as the most common culprit; while in instances where only one factor contributed, improper storage was most frequently implicated. Conclusion: The prevalence of B. cereus outbreaks remained relatively consistent throughout the studied period. Understanding the types of foods, causative factors, and contributing elements leading to B. cereus outbreaks can help inform prevention strategies for foodborne illnesses. The majority of outbreaks were associated with rice- or flour-based foods in school canteens, suggesting contamination and improper storage during food preparation. Consequently, it is essential to prioritize continuous education for canteen staff on food safety, efficacious management, and proper practices. The implementation of comprehensive guidelines, encompassing multiple critical aspects, can potentially reduce the occurrence of B. cereus outbreaks.

New insight into the additives in preparation and reduction of shield slurry.

In the preparation of the slurry in the slurry shield (SSS) and subsequent reduction of the waste slurry produced by the slurry shield (WSSS), the additives in SSS improve the quality of filtration cake on the excavation surface, but they may also remain in WSSS, which have a negative impact on the reduction efficiency of WSSS. Therefore, it is valuable to establish the relationship between SSS and WSSS with additives as a link. Given this, this paper prepared WSSS with different dosages of additives and studied the influence of residual additives on the reduction. The residual additives made the reduction efficiency of WSSS worse, and the specific resistance to filtration increased by one to two orders of magnitude. The residual additives change the content of bound water or reduce the available sites of the soil particles that can be adsorbed by flocculants, leading to worse reduction results. To reduce the difficulty of reduction, combining polymer and bentonite as additives are recommended to prepare SSS. Polyaluminium chloride (PAC) acts by reducing bound water content through the interaction with residual bentonite, simultaneously augmenting PAM flocculation, which is recommended for reducing WSSS. This paper provides a reference for selecting materials used to prepare SSS and the subsequent reduction of WSSS.

Attribution Analysis of Household Foodborne Disease Outbreaks in China, 2010-2020.

Foodborne diseases have become a serious public health problem worldwide, and foodborne disease outbreaks have placed a heavy disease burden on China. Foodborne disease outbreaks occur most frequently among families in China. The objectives of this study were to analyze the cause of household foodborne disease outbreaks in China from 2010 to 2020 and to identify where preventive measures could be targeted. All data were obtained from the China Foodborne Disease Surveillance System Report. A total of 17,985 outbreaks, which resulted in 73,252 illnesses, 38,829 hospitalizations, and 1269 deaths, were reported in this period. Most household outbreaks of foodborne diseases occurred in May-October, and the highest number occurred in July (3620 outbreaks, 20%). The province with the highest number of outbreaks was Yunnan Province (4829 outbreaks), followed by Hunan Province (2264 outbreaks). The attribution analysis revealed that fungi (mainly poisonous mushrooms) were the most implicated food category, with 8873 (49.3%) cases. The second was poisonous plants and their products, with 1552 (8.6%) cases. Fungi were the primary etiologic agent, with 31,125 illnesses, accounting for 42.5% of the incidents. Inedibility and misuse (9423 outbreaks), unknown origin (2505 outbreaks), and improper processing (2365 outbreaks) were the main contributing factors causing outbreaks of foodborne diseases. The results show that southwest China was a high-risk area for household foodborne diseases. Therefore, public health institutions should strengthen supervision and food safety education of residents to reduce the outbreaks of household foodborne diseases.

[Status and related factors of overweight and obesity among children and adolescents aged 6-17 in Yunnan Province during 2016-2017].

OBJECTIVE: To understand the status and related factors of overweight and obesity in children and adolescents aged 6-17 in Yunnan Province. METHODS: From 2016 to 2017, 3463 children and adolescents aged 6-17 from 65 primary and secondary schools in 13 counties of Yunnan Province were selected by stratified cluster sampling method for face-to-face questionnaire survey, including 1716 boys and 1747 girls, 2098 elementary school students, 762 middle school students, 603 high school students, of which, 1368 students from urban area and 2095 students from rural area. The questionnaire included information including, weekly consumption of sugary drinks, sweets, puffed food, fruits, vegetables, breakfast, daily activities of moderate or high intensity, school sports, daily hours of playing video games and watching TV, daily sleep and outdoor activities. Height and weight were measured using standard method. SPSS20.0 was used for χ~(2 )test and multivariate Logistic regression analysis. RESULTS: The prevalence of overweight and obesity among children and adolescents aged 6-17 were 8.43%(292/3463) and 6.01%(208/3463) respectively. The overweight rates of male students and female students were 8.45%(145/1716) and 8.41%(147/1747) respectively, and the statistic was significant differently(χ~(2 )=0.001, P>0.05). The overweight rates of urban and rural children and adolescents were 11.99%(164/1368) and 6.11%(128/2095) respectively, and the statistic was significant differently(χ~2=37.04, P<0.01). The overweight rates of primary school, middle school and high school were 7.53%(158/2098), 9.32%(71/762) and 10.45%(63/603) respectively, and the statistic was significant differently(χ~2=6.15, P<0.05). The obesity rates of male and female students were 7.11%(122/1716) and 4.92%(86/1747) respectively, and the statistic was significant differently(χ~2=7.33, P<0.01). The obesity rates of urban and rural children and adolescents were 9.50%(130/1368) and 3.72%(78/2095) respectively, and the statistic was significant differently(χ~2=48.97, P<0.01). The obesity rates of primary school, middle school and high school were 7.67%(161/2098), 3.15%(24/762) and 3.81%(23/603), respectively, and the statistic was significant differently(χ~2=26.48, P<0.01). Multivariate Logistic regression analysis showed that cities(OR=2.025, 95%CI 1.646-2.492) and non-residential schools(OR=1.808, 95%CI 1.470-2.223) were associated with overweight and obesity in children and adolescents, both of which were statistically significant(P<0.05). CONCLUSION: The prevalence of overweight and obesity among children and adolescents aged 6-17 in Yunnan Province were high. Urban, non-residential school children and adolescents are more likely to be overweight and obesity.

Governance matters: Urban expansion, environmental regulation, and PM2.5 pollution.

Increasing PM2.5 pollution in urban expansion threatens citizens' health. Environmental regulation has proven to be an effective tool to directly combat PM2.5 pollution. However, whether it can moderate the impacts of urban expansion on PM2.5 pollution, in the context of rapid urbanization, is an interesting and unexplored topic. Therefore, this paper constructs a Drivers-Governance-Impacts framework and explores in depth the interactions among urban expansion, environmental regulation, and PM2.5 pollution. Based on 2005-2018 sample data from the Yangtze River Delta region, the estimation results of the Spatial Durbin model imply that (1) urban expansion has an inverse U-shaped association with PM2.5 pollution. The positive correlation may reverse when the ratio of urban built-up land area hits 0.21. (2) Of the three environmental regulations, investment in pollution control has little impact on PM2.5 pollution. Pollution charges and public attention exhibit a U-shaped and inverted U-shaped relationship with PM2.5 pollution, respectively. (3) In terms of moderating effects, pollution charges can exacerbate PM2.5 pollution from urban expansion, while public attention can inhibit it through its monitoring role. Therefore, we suggest that cities adopt differentiated strategies of urban expansion and environmental protection according to their urbanization levels. Meanwhile, appropriate formal regulation and strong informal regulation will help improve air quality.

Epidemiology of foodborne bongkrekic acid poisoning outbreaks in China, 2010 to 2020.

Foodborne bongkrekic acid (BA) poisoning is a fatal foodborne disease in China. From 2010-2020, a total of 19 BA poisoning outbreaks were reported to the China National Foodborne Disease Outbreak Surveillance System. These outbreaks involved 146 illnesses, 139 hospitalizations, and 43 deaths, with a case-fatality rate of 29.5%. Approximately 73.3% of the outbreaks occurred in South and Southwest China. Homemade fermented corn flour products, tremella, and sweet potato flour and corn flour products (jelly) caused more early outbreaks, and novel vehicles (wet rice noodles and Auricularia auricula) were associated with later outbreaks in the study period. Outbreaks most frequently occurred at home (79.0%) and in restaurants (21.0%). The prohibition of traditional processed homemade fermented corn flour products and improvement in bongkrekic acid poisoning case identification and early treatment have resulted in a reduction in the case-fatality rate.

Global trends in the incidence and mortality of asthma from 1990 to 2019: An age-period-cohort analysis using the global burden of disease study 2019.

Background: Asthma is a major global health challenge. The global strategic management and prevention of asthma report has been published, but health system planning for asthma requires a careful assessment of asthma epidemiology. This study described the incidence and mortality of global asthma from 1990 to 2019. Methods: Based on data from the global burden of disease study (GBD) 2019, we present spatial and temporal trends in asthma incidence and mortality for the world and its 204 countries and territories from 1990 to 2019. Meanwhile, age-period-cohort analysis was used to explore factors influencing asthma incidence and mortality. Results: From 1990 to 2019, the incidence of asthma decreased from 601.20 per 1,00,000 to 477.92 per 1,00,000, and the mortality of asthma decreased from 8.60 per 1,00,000 to 5.96 per 1,00,000. High sociodemographic index (SDI) areas have higher age-standardised asthma incidence and low sociodemographic index areas have higher age-standardised asthma mortality. The age-period-cohort analysis results showed that the relative risk (RR) of incidence was high in children and the RR of mortality was high in elderly individuals. The RR of both asthma incidence and mortality showed a decreasing trend over time. The RR of asthma incidence in the recent birth cohort was higher than that in the previous birth cohort. The RR of asthma mortality continued to decline with the change in the birth cohort. Conclusions: Global asthma incidence and mortality decreased from 1990 to 2019. The decline in asthma incidence was mainly attributed to age effects and period effects, and the decline in asthma mortality was mainly attributed to period effects and cohort effects. Focusing on the risk of incidence in children and the risk of mortality in the elderly, promoting healthy lifestyles and controlling environmental risk factors can help to better control asthma.

Identification of the Key Genes Involved in the Tumorigenesis and Prognosis of Prostate Cancer.

Background: Prostate cancer (PCa) is a malignant tumor in males, with a majority of the cases advancing to metastatic castration resistance. Metastasis is the leading cause of mortality in PCa. The traditional early detection and prediction approaches cannot differentiate between the different stages of PCa. Therefore, new biomarkers are necessary for early detection and clear differentiation of PCa stages to provide precise therapeutic intervention. Methods: The objective of the study was to find significant differences in genes and combine the three GEO datasets with TCGA-PRAD datasets (DEG). Weighted gene coexpression network analysis (WGCNA) determined the gene set and PCa clinical feature correlation module utilizing the TGGA-PRAD clinical feature data. The correlation module genes were rescreened using the biological information analysis tools, with the three hub genes (TOP2A, NCAPG, and BUB1B) for proper verification. Finally, internal (TCGA) and external (GSE32571, GSE70770) validation datasets were used to validate and predict the value of last hub genes. Results: The hub gene was abnormally upregulated in PCa samples during verification. The expression of each gene was favorably connected with the Gleason score and TN tumor grade in clinical samples but negatively correlated with the overall survival rate. The expression of these genes was linked to CD8 naive cells and macrophages, among other cells. Antitumor immune cells like NK and NKT were favorably and adversely correlated with infiltrating cells, respectively. Simultaneously, the GSCV and GSEA indicated that the hub gene is connected with cell proliferation, death, and androgen receptor, among other signaling pathways. Therefore, these genes could influence the incidence and progression of PCa by participating in or modulating various signaling pathways. Furthermore, using the online tool of CMap, we examined the individual medications for Hughes and determined that tipifarnib could be useful for the clinical therapy of PCa. Conclusion: TOP2A, NCAPG, and BUB1B are important genes intimately linked to the clinical prognosis of PCa and can be employed as reliable biomarkers for early diagnosis and prognosis. Moreover, these genes can provide a theoretical basis for precision differentiation and treatment of PCa.

Population attributable fractions for risk factors and disability burden of dementia in Jiangxi Province, China: a cross-sectional study.

BACKGROUND: In view of the fact that there is no effective treatment for dementia, the number of years that dementia patients have to live with dementia will gradually increase for the rest of their lives, and the disability loss caused by dementia will increase. It is urgent to study the influence of risk factors on dementia by making use of the potential of prevention. The purpose of this study is to quantify the burden of dementia disability attributable to risk factors by assessing the population attributable fractions (PAFs) in Jiangxi Province, which is one of the regions of moderate aging process of China. METHODS: The prevalence data of nine risk factors were obtained through the Sixth National Health Service Survey in 2018, which covered 2713 older people. Levin's formula was used to calculate the PAF for each risk factor for dementia. We adjusted the PAF for communality between risk factors, and used these values to calculate overall weighted PAFs and the years lived with disability (YLDs), which were attributable to nine risk factors. RESULTS: The number of dementia cases and their proportions that can theoretically be prevented by nine identified risk factors were 111636 (99595-120877) and 66.8% (59.6-72.3), respectively. The total YLDs of dementia were estimated to be 61136 (46463-78369) (males: 36434 [24100-49330], females: 23956 [14716-34589]). Physical inactivity (11639 [8845-14920]), low social contact (9324 [7086-11952]), and hearing loss (5668 [4307-7265] were the top three contributors to dementia. CONCLUSIONS: The moderate aging areas represented by Jiangxi Province have great potential in the prevention of dementia. Targeted interventions and management of risk factors can effectively reduce the disability burden of dementia.
